35) Effect of complexing agent In general, it is well-established that metal corrosion or oxidation is accelerated in the presence of oxidative and complexing agents.
Kimberly-Clark built upon this concept, though, when, in the early 2000s, it developed its special acrylic latex binder system for airlaid, with common table salt (sodium chloride) replacing boric acid as the complexing agent.
Some specific topics covered include the role of arginine as a complexing agent in copper CMP, the effect of copper migration in a field-induced dielectric failure, and the formation of air gap structures using PECVD.
